Between Kontakt, Falcon, and HALion, which is best for manipulating drum loops and vocal chops? (for Acid, Big Beat)

[UltimateOutsider]

I am going to be starting a 90s Acid/Big Beat-style project soon, and it's going to involve a bit of sample-fu regarding drum loops and vocal chops. Lots of time-stretching and pitch-shifting and stutter-type effects.

I own Kontakt 6, HALion 7, and Falcon 2026. I've used all of them before for making drum kits and simple instruments (sampled pianos and synths), but I've never done any real sample manipulation with them.

Which of these samplers would be best (or worst) for this kind of work? It's going to be a learning process for me regardless, but I want to know which of my tools to start investing time in.

Thanks!
